Alphabetical order
An
alphabet usually has a convential order of letters.
Alphabetical order of words and phrases is based on this order in combination with the principle of
lexicographical order.
A blank space is treated as a character that comes before the letters.
Conventions may vary where to position digits and special characters.
A common order is:
- blank space\n*symbols\n*digits\n*letters
A more advanced system may consider numbers as such instead of just considering the digits; in that case 100 does not come between 10 and 11, but after 11. This can be extended to
Roman numerals.
However, if a number is spelled out it is treated as a word.
For example:\n*$2.99 \n*2 dollars 99 cents\n*2.99\n*two dollars 99 cents
Normally capitals and lowercase letters have the same position. On computer systems sometimes a crude system is used, e.g. based on
ASCII order. In that case "a" comes after "Z", see e.g.
[1].
